So extra background, I was put off by proxmox’s weird steps to get ISO’s onto the system via USB so I was like “I am not touching the backup stuff” and just rolled my own (I treat the VMs/containers on my proxmox server like individual servers and back them up accordingly and do not back up the underlying proxmox instance itself).

I see proxmox has a similar pruning setting to Restic, and it exports the files like incus. So I’d say yes, proxmox is one-stop-shop for backup while with incus you have to put its container export options and restic together and put that in a cron job.

Still hard to say what I’d definitively tell a newbie to go with. I found (and still find) the proxmox ui daunting and difficult while the incus UI makes much more sense to me and is easier (has an ISO pulling system built in for instance. But as you’ve pointed out - proxmox gives you an easy way to have robust backups that takes much more effort on the incus side.

As backups are paramount, proxmox for a total newbie. If someone is familiar with scripting, then incus - because it needs scripted backups to be as robust as proxmox’ backups. @barnaclebill@lemmy.dbzer0.com this conclusion should help you choose proxmox (most likely)!
